Title: Detector for number of commodity on shelf therefor
Inventor: HAYAKAWA FUMIO
IPC: B65G1/00
Filed: 1980-03-26
Abstract: PURPOSE:To make it possible to automatically and speedily count the number of commodities stored on a commodity shelf by a method wherein strain gauges are attached to a portion of the commodity shelf to detect the flexture thereof. CONSTITUTION:Strain gauges 11a and 11b are attached to the portion of a commodity shelf 23 where distortion is produced when commodities are mounted, and strain gauges 11c and 11d to a portion of a wall 21. These strain gauges 11a-11d are connected into a bridge circuit 11, whose output ends (a) and (b) are connected to an amplifier 13. When commodities are mounted on the commodity shelf 23, the resistance values of the strain gauges 11a and 11b vary in response to the distortion resulting from the bend of the commodity shelf 23 according to the overall weight. Accordingly, a voltage proportional to the number of commodities is outputted from the output ends (a) and (b), amplified 13 and rectified 14 before being inputted to a dividing circuit 15, and the number of commodities is displayed on a display device 18.

IPC: G11B20/10
Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To obtain a simple VTR system by enabling all data to be read out at a speed n-times as high as the recording time and yet enabling reproduction at the same speed as the recording time. SOLUTION: Signals of heads opposite to one another at 180 deg. are amplified by their respective amplifiers 12, and are then alternately changed by a head switch signal to be led to a reproducing demodulation circuit 13. A recorded data of each track as the digital data demodulated by the reproducing demodulation circuit 13 has a data rate which is slightly different from but almost the same as the recording time, and is outputted individually in parallel into a 4-channel system to be stored once in a memory circuit 14. In order to expand and decode the compressed data, if, for instance, 10 tracks constitute 1 frame, every 10 tracks in the lump are inputted to expanding and decoding circuits 15.  Then, for the purpose of rearranging the data stored in the memory circuit in order of the original tracks in turn, a memory read-out signal from a memory control circuit 16 is controlled to read out the memory to separate picture decoding circuits in a unit of 10 tracks in order of the original tracks at a data rate for the usual reproducing time.

The total visual angle range corresponds to the set of such continuous theta, theta', theta''. The character and shape displayed on the transparent conductive film 3 are visible in the magnified visual field range.

Title: Heating device for vehicle
Inventor: HAYASHI YOSHIMASA
IPC: B60H1/02
Filed: 1984-03-02
Abstract: PURPOSE:To enable to perform stable heating even during idling and to enable heating to become effective rapidly through efficient circulation of only warmed coolant to a heater core during heating-up, by a method wherein heating of the interior of a vehicle is conducted through utilization of coolant of a boiling cooling system. CONSTITUTION:During idling of an engine and running at a low speed, a circulation pump 31 is driven at a specified rotation speed and therefore, a given amount of coolant is always fed to a heater core 26 from a water jacket 2 to maintain a stable heating capacity. During the starting of an engine, the coolant in the water jacket 2 is not agitated, and the coolant, increased in temperature, in the upper part of the jacket 2 is efficiently circulated to the heater core 26. Even during heating up of an engine, wherein the whole coolant in the jacket 2 is not completely heated, heating can be conducted, and this enables heating to become effective early. In boiling and cooling, the capacity of the jacket 2 is decreased, and this causes the coolant to be heated in a short time and permits heating to become effective more earlier.
